Apache does not have the permission to copy files from a mounted directory

Question

My application on the server wants to copy a file from a remote directory mounted by sshfs to a local directory. The application code:

shutil.copy('/data/somdir/somefile.txt','/var/www/App/localfolder' )

The permissions of /data is as follows:

drwxrwxrwx   1   1027 root  4096 May  6 10:16 data

So every user(including Apache) should able to access the folder, but in the logfile I get:

IOError: [Errno 13] Permission denied

Some edits and updates on my question:

I set allow_other when mounting via SSHFS, and all the directories along the path to the source file have permissions of at least 755.So any use has read access to it.

Answer 1

mount with option allow_other.

If you rely on these permissions being enforced, add the option default_permissions.
